Intel Skylake Core i7-6700K IPC & Overclocking Review
Today we finally get to share with you our Intel Skylake experiences. As we like to, we are going to focus on Instructions Per Clock / IPC and overclocking this new CPU architecture. We hope to give our readers a definitive answer to whether or not it is time to make the jump to a new desktop PC platform.
We make a lot of comparisons on the following graphs and will try to keep it from getting convoluted. Memory frequency scaling has a lot of impact in different testing scenarios, so we try to show that as it might very well influence your upgrade decision about this new Skylake platform. As is usual, we show our past and current processors compared at the same 4.5GHz frequency so you can focus on IPC since most HardOCP readers will be overclocking their CPUs. Also we will show you just how successfully we could overclock this Skylake CPU and keep it 100% stable under abusive full load conditions.
Keep in mind that specified memory speed for the Skylake 6700K and 6600K CPUs is 2133MHz DDR4. We will be showing speeds down to 1866MHz to give us an "apples to apples" comparison. It is highly unlikely that you would be using it at memory clocks this slow.
ASUS Z170-Deluxe Testing System
For all our Skylake Core i7-6700K testing we used a new ASUS Z170-Deluxe motherboard and Corsair Dominator Platinum DDR4 memory rated at 3600MHz with 18-19-19-39-2T timings at 3600MHz. Note that these Corsair memories will not have the orange heat spreader when in retail sale. The spreader will be the more common silver color.
